mrtg to count packets

I need to setup mrtg to count packets,
anyone done this.
This is how I use cfgmaker to make mrtg.cfg file to track bandwidth
any ideas how to make it count packets per second/min/hour?

cfgmaker --global “WorkDir: /home/mrtg/test” --global “Options[_]: growright” Canopy@> mrtg.cfg :?:

Get a SNMP viewer.
Use it to find the OID of your desired information.
Graph the OID in MRTG.
